Democratic Senate candidate Elizabeth Warren was listed as a minority in the University of Pennsylvania’s “Minority Equity Report” in 2005.

The report was published years after Warren left the school. The publication listed past winners of its “Lindback Award,” and the names of minority professors were listed in bold and italics. Warren, who won the prize in 1994, was listed in the font used for minorities.

Warren taught at the University of Pennsylvania law school from 1987 to 1995.

Warren has come under increasing scrutiny for listing herself as a minority in a law school directory, the Association of American Law Schools, from 1986 until 1995, the year she was hired by Harvard Law School.

A genealogist has said Warren was 1/32 Cherokee, and Warren has said she is proud of her Native American lineage, but there has not been any proof of the claim.

Warren’s Republican opponent, U.S. Senator Scott Brown, has been questioning whether Warren misrepresented herself or gained any career advantages through her minority status.

The Warren campaign has released statements from professors and deans at each school Warren taught at, stating that her minority status was not a factor in her hiring.

The Boston Globe reported that Warren listed herself as “white” when she taught at the University of Texas law school from 1981 to 1991.
